Struggling freshwater fish populations in the Mekong River catchment received a boost earlier this month when a team of scientists and fisheries specialists released 1,500 captive-reared juvenile fish into Tonle Sap Lake in Cambodia.
Experts say the release is the first step in rejuvenating the Mekong’s depleted fish populations and fisheries, which have been suffering in recent years due to overfishing, drought, habitat destruction, and the impacts of upstream dams on the Mekong River’s natural flow. |

The fish, including critically endangered Mekong giant catfish and giant barb, and endangered striped river catfish, were released into a series of fish sanctuaries and community conservation areas that protect crucial fish nursery habitat in Tonle Sap Lake, the world’s most productive inland fishery.
Long-term survival of the Mekong’s threatened fish species will also depend on protection of migration corridors and upstream spawning grounds, and on maintenance of free-flowing and connected watercourses, say experts. |
